lMl'ilfoVElillENIT, IN HARVESTERS.V

Specification forming part of Letters Patent No..46,l70, dated Jmmarv Sl, 1.865.

Tl'o all whorn itv may concern: I' l Be it known that I, ALoNzo Woon, of Henrietta, in the county-0f Monroe and State of New York, have invented a new and useful Im- I' provenient in Adjusting the/Reels of Harvesters; and I` do hereby declare that the following is a full'and exact description thereof, reference being had to the accompanying drawings,

lmaking part of this specification.

. In fields of grain the straw 1s usually of vary- 4 ing height, being tall in sonic port-ions and Short in. oth-ers. In order to ina-ke the reel work properly in. inclining 4the 'straw to the table'or plattirin, it is necessary .to raise and lower it to adapt it to these varying heights ofthe stawl In most liarvesttus the recl is made to adjust higher or lower by removing a ,bolt from oneV adjustinghole to another; butin such cases it is obi/'ions that the reel is not automatically under eontrol'lof the driver, but is fixed in its po# sitioii and cannot be adapted to the purpose before indicated.

It is the object of my invention to so arrange the reel that it canbe raised or lowered at pleas ure by the driver without removing from his seat by merely turning ahand-whe'el in such a manner as tov adapt the same to the varying height of the grain as it is -being cut.

As represented in the drawings, AB4 are the supporting-Wheels; C, the main frame, andD the table or platforimwhich parts do not dier essentially from the corresponding parts in or dinary' harvester's. 4

On each' side of the table orplatform D,- at a suitable position, areerectcd standards E E, to

whose tops are jointed, at a, arms G G. For.

the purpose of bracing Aand strengthening the arms I prefer to connect with them at the rear vertical end pieces, 'c l), and angular pieces c o, Whicireonnect ncarthe front end, the whole forming triangles, as 'clearly represented; but this is not absolutely essential, and any desired modification may beI employed'. The front ends of the arms G G forinthe bearingsfor the ordinary rcel, H, which is' operated in any usual or desirable manner.

In the rear ofthe standards E 1G are othei similar stai'idards, I'I, which i'orin bearings for ajshaft,. K, having at opposite ends, ina position corresponding with the arms, ,pulleys f j',-

Fig. 3, provided with square bearings g g; or, what is thcsanie in effect, the-shaft itselfmay be made square, andthe pulleys dispensed with. Around the square bearings wind chains or cords M Ml once or more, so as to prevent slip-- ping, one end connecting with tlie'arms G A(i,

while the other connects with the angular bracesc c, or their equivalent.

It is obvious that as the shaft K is turned in one direction or the other the chainswill be correspondingly wound or unwound and the 'arms G G moved up or down, thereby adjusting the reel H higher or lower. i

In order tov operate the shaft K easily I secure rigidly on its end, within reach of thc .i

drivers seat, a. .hand-wheel, N, similar to the hand-,Wheelof a ear-brake; On its inner edge I providet e ri-m of this Iwheel with ratchetteeth k k, into which catches the pawl Z of a j spring-lever, P, that yields away from the wheel. In raising thc reel, (as indicated by red lines, Fig. 1,) it is only necessary to take j hold of the handwheel and move it forward, the spring-lever yielding to allow it to pass and holding it in any desired position whengraised;

butin lowering the reel the lever is seized and held back, thus allowing the hand-wheel to v turn freely, and the reel will fall of itsown weight. j A

lIt is manifest that an equivalent device to thev chains M M may be employed with a similar 'eectfsuca for instance, asa cog-rack sccured to the arms G G,'With a'pinion on shaft K gearing'with it.

The advantages of this .arrangement are obvious. The driver hasthe reel Vcompletly under his control, and .can raise or lower itat pleasure and with but little effort by either turning the hand-Wheel or depressing the lever. He can ,thus cause the reel to work uniformly on lthe inequality 'ofvheight'of the straitr in difu ferent parts of the iield--an effect that, so far as I am aware, has never vbefore been accomplished. In all harvesterswith which I am acquainted the adjustment of the reel has been .arbitrary and without referento adapting-it Q `476mm -ng'abolt from one hole to av'nother, or in some equivalent Way. v I do notc1ai1n,'b1oadly, adjusting the reel of :L harvester higher 01' lower; but' Adjusting the reels of harvesterS-sojs to equivalent,v and pmvl-lever l?, o1' equivalent," ,Y
